Apink made their debut six years ago on April 19, 2011 with Seven Springs of Apink and the title track I Dont Know. Since then they have branched out into solo activities in music, acting, and variety and gained love for their signature concept.

Earlier this week, it was revealed that Apink would be giving Pink Pandas a special gift in honor of their sixth debut anniversary. Apink debuted on April 19, 2011 with their EP Seven Springs of Apink and title track I Dont Know. Over the past six years, the group has received a great deal of love for their consistently innocent, youthful image and undeniable talent.

The members also thoughtfully dedicated handwritten letters to their fans, thanking them for their love and support over the past six years.
